termed by stamping from thin sheet metal such as brass into an integral whole com- 5 prising a semi-spherical body portion 29, a pedestal i and horizontally disposed base or leg portion '31. {The face'ofeach of the brackets is in a" vertical plane'and of a cross-sectional extent slightly less than that of the caps i l and .15 designed to rotate closely'adjacent thereto. The areaembracei'l by the bracket tace'29 is sufficiently large to nich de the pawls 20, here shown as pro vided w th pivots 21 and abutmentslfi), so as to effectually house the same 'andform a casing within which such parts revolve and function. V One of the brackets, shown at thelright hand of the hgures'm the drawing, is pro vided with a bearing stud 32 of metal having its end 32 reduced and seated within the central portion-of the bracket body 29 and upset or rivetedto prevent its dislodgement. T he companion bracket at the left hand end is provided with a bearing stud 33 similarly mounted within the bracket but differing from the stud 32 in that it is of a greater length and projects slightly be yond the face of the bracket and is also provided with a recess or slot 34 in its side wall ad acent to its end, the said recess cooperac 'ing with the pawels 20 to permit the rotation of the roller in one direction and to check its rotation inthe other, the action of the pawls being controlled by gravity and con tritugal force in the well knownjmann'er without the use of actuating springs. The

" V projecting end oi the bearing stud 33 is accommodated within the cavity at 18 provided by the inward depression of the metal. This projecting off the stud end into the cavity brings the pivotal points of the pawls 20 into a plane which includes the stud and effectually prevents any interference with; the operation of the jv roller by the accidental dropping of the pawls over the end of the stud. r j.

Thespring 24 isnot only'placed under Vangular tension by thetwiriding? of the roller after being seated within the brackets butits length is suchthat it is. at all times under longitudinal tension. whereby to. hold the rolleras an entirety resiliently'pressed against the left hand bracket, thus prevent- .ing any tendency of the mechanism toirattle in case thebraekets should not be accurately adjusted asto position. It will be understood that the two. ends of the axle 22 are frictionally fixed 1 within the" "bearing studs 32 and 33'against withdrawal and turning,

they each-being slightly deformed as inch in c the bearing studs.
